Vehicle Speed Display Layout for Recognizable Control Speed Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face a burden in remembering vehicle speed ranges corresponding to preset conditions for vehicle control, especially in autonomous driving scenarios, as existing display systems do not effectively convey this information in a visually recognizable manner.
Innovation Solution
A vehicle speed display device and method that generates and displays a first image indicating the vehicle's speed and a second image showing the corresponding speed range on a display unit, with the second image positioned alongside the first, allowing easy visual recognition of the speed range, and optionally includes images for specific autonomous driving functions and states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle speed conditions are described in the vehicle owner's manual, then the driver can obtain information about speed ranges, but the driver must remember this information which creates a burden
Solution Approach 1:
The system pre-prepares and displays the vehicle speed range corresponding to the current vehicle speed condition on the display unit before the driver needs to use this information. The display shows the speed range in advance, so when the driver needs to know the applicable speed condition, the information is already visually presented, eliminating the need to remember it from the manual.
2Loss of information
If the vehicle speed range is displayed on the display unit, then the driver can easily recognize the information, but the display system becomes more complex
Solution Approach 1:
The system merges the display of vehicle speed condition information with the existing vehicle speed display functionality. By integrating the speed range display into the current display unit that already shows vehicle speed, the system avoids adding separate complex display mechanisms while still providing the needed information to reduce driver memory burden.

AI summary
A vehicle speed display device is provided in a vehicle capable of executing vehicle control. The vehicle speed display device includes a first image generation unit configured to generate a first image indicating a vehicle speed of the vehicle and a display range of the vehicle speed; a second image generation unit configured to generate a second image indicating a vehicle speed range corresponding to a preset vehicle speed condition regarding the vehicle control; and a display control unit configured to display the first image and the second image on a display unit of the vehicle so that the second image is disposed along the first image.
